What is raglan sleeve?

A raglan sleeve is a type of sleeve that extends in one piece the full length of the garment, from the collar to the underarm. It is characterized by a diagonal seam that extends from the neckline to the underarm, creating a triangular shape. Raglan sleeves are commonly used in sportswear, sweaters, and t-shirts as they provide a more comfortable and relaxed fit compared to set-in sleeves.

Raglan sleeves were first popularized by Lord Raglan, a British officer during the Crimean War, who lost his arm in battle and needed a more comfortable and practical sleeve design. The design allows for greater freedom of movement and is often seen in activewear and athletic gear to allow for greater range of motion during physical activity.

Raglan sleeves are often used in sewing patterns as an alternative to set-in sleeves, as they are easier to sew and require less shaping. They can also create a more modern and stylish look, and are often used in trendy and contemporary fashion designs.
